Ice conditions showed that the ice edge exceeded its normal mean position north of 71 degrees N in the Greenland Sea and in the western Barents Sea. Severe ice conditions existed east and north of Vestspitsbergen. Refreezing had begun north of 71 degrees N in the Greenland Sea. An ice chart is included to show observed conditions. Author
